Thanks everyone, i still dont know what ill do.
Yes im on a true street tire, running a 315/35-17
Yes its a stock t-5 for now, and i have a spare.
When the day comes that i break both of those i may do an astro A5 kit or 4r70w swap.

I want to ask. If i do 351 and 205 heads or 408 and 170 heads

Agreed.  Would be usable with 351ci and the big heads, but far from ideal.  Would not even think of that cam in a 408.
